Individual Computers: Delfina Flipper

The Delfina flipper is developed in cooperation with the developer team
of Petsoff in Finland and Individual Computers. Individual computers
licensed the original hardware design from Petsoff and improved upon
it. The Delfina flipper comes on two boards, the first board is the
sound card itself, whist the second is the flipper interface card. The
flipper card allows the Delfina to be used in a Zorro II slot or in a
PCI slot such as those on PCI busboards or even in a Pegasos. It can
also use the clock port in the A1200. It offers all the features of the
Delfina Plus, and more. The card contains a fast 67.73Mhz (prototype
versions were 73.7Mhz but suffered from heat problems) Motorola DSP
(56002) which 96Kb of 12ns SRAM that is capable of 220 MOPS. Sound
playback is via a 16bit 48Khz codec. Early prototype versions of the
card required frequencies other than 48Mhz, 44.1Khz and 32Khz to be
played back by re-sampling however this is not required on the release
version due to an updated CS4321A codec. This sound card is capable of
playing more AHI channels than any other Amiga sound card, partly due
to the redesigned Zorro II interface compared to earlier versions of
the board which has nearly doubled the performance. As mentioned, the
card can also be connected to the clock-port in an A1200, however a
towered A1200 is highly recommended because the physical dimensions of
the card do not allow proper mounting of the card in a standard A1200
case. The A1200 clockport cannot reach the performance of the Zorro II
bus, however it is still enough to playback several AHI channels and of
course playback MP3 files. For connection to the A1200's clock port an
optional connection kit is required.
